750-461 WAGO, 2-channel RTD module, (resistive temperature device)
2-Channel Analog Input Module
Description
This analog input module directly connects to Pt resistance sensors.
Two- or three-wire sensors can be connected.
The module automatically linearizes the entire temperature range. A sensor error (short circuit, line break or measurement range overflow) is indicated by a red LED.
A green LED indicates readiness for operation and error-free communication with the coupler.
The shield directly connects to the DIN-rail.
